A dental irradiation device comprises a first light emitting unit for emitting blue light adapted for light hardening of a dental material. The device further comprises a second light emitting unit and an image sensing unit which are adapted for cooperation with each other for simultaneous illumination and image capturing. The device facilitates hardening of dental materials and provides, inter alia, additional diagnostic functions.

Dental irradiation device and system

A device for dispensing a dental composition comprises a piston for extruding a component of the dental composition from a container. The device has a roller drive for displacing the first piston. The roller drive comprises cooperating first and second rollers, and each of the rollers have a roller surface with a radial rib profile. The rollers are arranged for rolling with their roller surfaces on one another. The invention may help providing for a relatively reliable and compact device.

Device for dispensing a dental composition

A system comprises an automatic mixing and dispensing device for a dental substance, and a material container. The mixing and dispensing device comprises a reservoir for receiving the dental substance, and first and second pressure plates. The material container has first and second material chambers for containing components of a material. The first and second material chambers have first and second cross-sectional chamber areas. At least one of the first and second cross-sectional chamber areas is smaller than smallest surface area of the first and second pressure plates. The system helps facilitating preparation and handling of dental materials.
